A: Precautions
1.
This medication should not be used by pregnant women.
It is contraindicated in cases of diabetic coma and before or after surgery.
2.
Patients with renal impairment must inform their physician and undergo regular liver and kidney function tests.
3.
This medication should be taken with meals.
4.
Gastrointestinal disturbances (nausea, abdominal pain, diarrhea) may occur, but taking it with meals can help mitigate these effects or allow for dosage adjustments.
5.
This medication may reduce the absorption of Vitamin B12; therefore, if taken long-term, it is advisable to check Vitamin B12 levels in the blood annually.
6.
Avoid excessive intake of alcoholic beverages.
7.
If there are any issues, please consult your physician or pharmacist immediately.
A: Side Effects
At the beginning of treatment, gastrointestinal discomfort such as loss of appetite, nausea, vomiting, and diarrhea may occur (>10%).
A small percentage of individuals may experience a rash (1-10%).
Generally, these symptoms resolve after about ten days of continued use.
Taking the medication with meals or immediately after can also help alleviate gastrointestinal discomfort.
The most serious and concerning side effect of this medication is lactic acidosis.
Although the incidence of this side effect is quite low (approximately 3 cases per 100,000 per year), it can lead to a 50% mortality rate among those affected.
Therefore, if this side effect occurs, it is crucial to notify a physician immediately.
Symptoms of lactic acidosis include fatigue, malaise, muscle pain, difficulty breathing, drowsiness, and sudden gastrointestinal discomfort.
More severe cases may result in decreased body temperature, low blood pressure, and bradycardia.
A: Blood Sugar Monitoring
Self-monitoring of blood glucose allows you to quickly know your blood sugar levels at any time, which can guide adjustments in insulin dosage and dietary intake, thereby achieving good control of diabetes and reducing the risks of hyperglycemia and hypoglycemia, as well as preventing long-term complications.
- For well-controlled individuals: Measure fasting, postprandial, and bedtime blood glucose once or twice a week.
Daily monitoring is optimal.
- For poorly controlled individuals: Measure blood glucose four times a day, including fasting in the morning, at 10 AM, at 3 PM, and at bedtime or 9 PM, and adjust treatment as needed.
- Increase testing frequency during illness or vigorous exercise.
- Record each measurement to provide data for your physician to adjust medication dosages or to contact healthcare personnel for immediate dosage adjustments.
- Blood glucose meters and supplies can be purchased from medical supply stores.
A: Dietary Therapy
A balanced diet is recommended, with an emphasis on high-fiber foods to slow carbohydrate absorption, control weight, and incorporate moderate exercise such as brisk walking, slow walking, strolling, or jogging to promote circulation.

More Info

When taking Glucophage (Metformin), there are several essential guidelines and precautions that patients should be aware of to ensure safe and effective use of the medication. Glucophage is primarily prescribed for managing type 2 diabetes by improving insulin sensitivity and reducing glucose production in the liver. Here are the key points to consider:

Dosage and Administration
1. Timing: Glucophage should be taken with meals to minimize gastrointestinal side effects, such as nausea and diarrhea. It is typically recommended to take it during or immediately after meals. This helps to reduce the risk of gastrointestinal discomfort and enhances the medication's effectiveness.

2. Dosage: The starting dose is usually low, often around 500 mg once or twice daily, which can be gradually increased based on blood sugar levels and tolerance. The maximum recommended daily dose is generally 2000-2500 mg, depending on the specific formulation.

3. Frequency: Patients are often advised to take Glucophage two to three times a day, depending on their prescribed dosage and meal patterns.

Side Effects
Patients should be aware of potential side effects, which can include:
- Gastrointestinal Issues: Common side effects include nausea, vomiting, diarrhea, abdominal pain, and loss of appetite. These symptoms often improve over time or can be mitigated by taking the medication with food.

- Vitamin B12 Deficiency: Long-term use of Metformin can lead to decreased absorption of Vitamin B12. Regular monitoring of B12 levels is recommended, especially if the medication is taken for an extended period.

- Lactic Acidosis: Although rare, lactic acidosis is a serious condition that can occur, particularly in patients with renal impairment or other risk factors. Symptoms include fatigue, muscle pain, difficulty breathing, and abdominal discomfort. Immediate medical attention is required if these symptoms occur.

Monitoring Blood Sugar Levels
Self-monitoring of blood glucose is crucial for patients taking Glucophage. Here’s how to effectively monitor:
1. Blood Glucose Testing: Patients should regularly check their blood sugar levels using a glucometer. The frequency of testing can vary:
- Well-Controlled Patients: Testing once or twice a week, including fasting and post-meal readings.

- Poorly Controlled Patients: Testing four times a day, including fasting, before meals, and at bedtime.

- During Illness or Stress: Increase testing frequency to monitor for potential fluctuations in blood sugar levels.

2. Glucometer: Patients should invest in a reliable blood glucose meter and supplies (test strips, lancets) to facilitate regular monitoring. Keeping a log of blood sugar readings can help healthcare providers make necessary adjustments to the treatment plan.

Dietary Considerations
In addition to avoiding sugary foods and refined carbohydrates, patients should focus on a balanced diet that includes:
- High-Fiber Foods: Incorporate whole grains, legumes, fruits, and vegetables to help regulate blood sugar levels.

- Healthy Fats: Opt for unsaturated fats found in nuts, seeds, avocados, and olive oil while limiting saturated and trans fats.

- Portion Control: Be mindful of portion sizes to manage caloric intake and maintain a healthy weight.

General Recommendations
- Alcohol Consumption: Limit alcohol intake, as it can increase the risk of lactic acidosis and affect blood sugar levels.

- Regular Check-Ups: Schedule regular appointments with healthcare providers to monitor kidney function and overall diabetes management.

Conclusion
In summary, when taking Glucophage, patients should adhere to prescribed dosages, monitor for side effects, and regularly check their blood glucose levels. A balanced diet and lifestyle changes are essential components of diabetes management. If there are any concerns or unusual symptoms, patients should consult their healthcare provider for guidance and adjustments to their treatment plan.
